Lip locking is the final stage of apisto territorial display. This only happens when both fish are of about equal strength. One will eventually win the tug of war and drive the other off. In the wild the loser leaves the area and no one gets hurt. In a tank the loser doesn't always have this option. If all 8 sq. ft. of tank bottom is claimed by the other fish, then the loser may be driven from one territory to the other. Keep an eye out for any hiding at the top of the tank or looking kind of beat up. You'll have to take him out or risk losing him. BTW studies with apistos have shown that males, if given the opportunity, will take over the entire bottom of a 200X50 cm (80X20") tank.
